SPECIFICATION forming part of Letters Patent No. 590,962, dated October 5, 1897.

Application filed December 29, 1896. Serial No.617,327. (No model.)

T all 1.0700712, t 71u07/ concern:

Be it known that I, JOHN A. BREEN, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Heaters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the let-ters and iigures of reference marked thereon, which forni part of this speciiication.

In the drawings, Figure 1 shows a perspective view of the rear portion of a heater constructed according to my plan,.the forward sections of the heater being removed. Fig. 2 shows a vertical central longitudinal section of the heater. Fig. 3 showsa verticalsection of one of the sections of the heater,the rearsection appearing behind the one shown. Fig. i showsdetails of draft-openings in doors employed in the construction, showing a front view of thc same. Fig. 5 shows a sectional view of the same construction. Fig. 6 shows details of the connections between the several sections of the heater and the manner in which the covering is secured.

Referring to the reference letters and figures in a more particular description of the device, 1 1 1, ttf-c., indicate the regular or intermediate sections of which the heater is composed, and 2 3 the front and rear sections. The intermediate sections are all similarin construction, asV well as' the front and rear sections, and the front and rear sections are somewhat similar to the regular sections, as will be noted by reference to the drawings. The regular and intermediate sections all have an inverted- U -shaped hollowiorin body, having cross-tubes 4, 5, 6, 7, and 8 and a central upright tube 9, extending from the crosstube S to the upper end of the section. Between the central tube 9 and the body portion of the section are provided also the short cross-tubes 10 and l1.

The tubes di, 5, G, 7, S, 10, and il are alterna-tely disposed on opposite sides of the section, as shown clearly in Fig. 2, whereby the heated gases and products of combustion are deiiected and caused to travel in an irregular course, so as to encounter the largest amount of exposed surface to be heated. The upper portion l of the hollow section-frame is reduced as compared with the lower portion 1b, so that there is a greater volume of water held by the section in its lower portion than in its upper portion. The lower portion of the section straddles the iire-boX A, and the lower ends of each side of the sectionframes are provided with hollow tooth-like projections 1212, tbc., which have an inclined upper surface and a substantially horizontal lower surface, as shown, and when these several sections are placed together these toothlike projections form ribs extending the full length of the sides of the fire-box. At the bottom of the iire-box is provided a grate B, and under the grate is the ash-pit O, formed by ash-pit walls c.

The endv sections 2 and 3 are similar to the regular sections, except at the lower portion below the lowest cross-tube .4a the space is iilled up with the wall 13, which is provided `with the two tooth-like ribs on its inner face 17, near the botto in of the section, and the sections are secured together, as well as the front and rear plates, hereinafter described, by bolts 1S.

It will be noted that each section is provided with a pair of lugs at each of the points indicated, one upon either side of the section, and the bolts 1S are of a length somewhat greater than the width of one section, so as to pass through the lug of one section and span the width of an intermediate section through the lug of the next section. By this arrangement the use of the long bolt is obviated and the objectionable expansion which results from the use of long bolts in heater constructions is eliminated. The lugs or projections 15, 16, and 17 are provided with two sets of openings, as will be noted upon ex- IOO amination of the drawings, so that these bolts can be readily placed and removed independently of each other.

The end sections 2 and 3 being similar and each being provided with a door-opening, the heater can be readily changed about, so as to be fired from either end, as may be desired. In the construction as shown the front end of the heater is closed by a front plate 2O and the rear end of the heater is closed by a back plate 21. The plate 20 is provided with an opening into the fire-box through the'opening 14 in the end section, closed by a door 22. It is also provided with clean-out openings closed by doors 23- and 24. The rear plate 21 is provided with openings 25 25 to afford smoke-passages, and these openings are covered from the outsideby a jacket 26, which extends downwardly on the outside of the plate 21 and furnishes areverse iiue 27. At the upper end the jacket 26 is provided with an opening connected by a short pipe 2S with the smoke-flue 29, andy in this short section of pipe is provided a damper 30. The smoke-tube 29 is extendedy down below the cross-pipe 28 and connectsl with the lower end of the reverse flue, as shown in the drawings.

It will be noted that the plate 21 closes'the opening 14 in the back end of the furnace and in the section 3 as the construction is arranged in Fig. 2. It is evident'that by slightly modifying the form and length of the jacket 26 and the lower end of the smoke-flue an` opening and a door might be provided through this plate, so that the heater could be fired from both ends in case a heater with a large number of sections was employed. Each-section of the heater is provided at its upper end at the highest point with an opening 31, to which the conducting-pipes can be attached or which may be connected with a druln to which the connecting-pipes are attached.

The return-pipes 32 are attached to the footof the rear section, as shown in Figs. l and 2, but in case of the use of a large number of sections in the same heater return-pipes might be attached to all four of the lower corners of the heater. b

For the purpose of supplying fresh air to combine with the products of combustionl above the iire there is provided in the lower side of the door 23, as shown at 23h, and inthe upper side of the door 22, as shown at 22, a series of openings with suitable slides or other means for controlling these openings. The slide is indicated by m on each of the doors.

Vhen these heaters are set up, they are to be covered with some non-conducting material or substance in'order to prevent radiation,land for this purpose I employ a plaster in which asbestos forms a large part of the material. the heater I provide a wire-netting w, which is passed over the heater and is fitted over the lugs or projections 15, 16, and 17, as shown in Figs. 3 and G, by having the lugs For securing thiscovering onv passed through the meshes of the netting before the bolts 18 are put in place. Vhen these bolts 18 are put in place, the netting is thereby firmly secured on the heater, and when the plastering is applied it surrounds the netting, so that the netting is embedded therein, and thereby the covering is formed and secured on the heater. More or less lugs may be employed between the netting w and the. heater, so as to hold the netting out of contact with the surface of the. heater and allow considerable portions of the plaster to take a position between the netting and the surface of the heater.

The use and operation of heaters of this description being well understood, specific description of operation may be omitted. It, however, might be not-ed that in the fire-box the. fuel is held out of contact with the body of the sections of the heater which absorbs the heat, and being so held out of contact by the tooth-like ribs or projections the fuel whichY liesy adjacent to the walls of the heater is not cooled to such an extent that it will fail toV properly consume with the fuel held in the center portion of the lire-box. The inclined upper surface of the tooth-like projections on the interior of the tire-box causes the accumulation of ashes-or dust to slide off,

' detrimental influence upon the combustion.

The arrangement of the cross-tubes of the sections on altern-ate sides of the section is suchas to deflect the products of combustion as they rise fromA the fire in such manner as to bring them in contact with asm-uch heat-absorbing surface as possible, whereby the best results are. attained. In order to prevent the products of combustion passing directly tothe smoke-exit openings 25 25, is employed a pair of plates40 40, which are of less length than that of the heater as awhole, which are placed through the openings close by the door 24 on top of the cross-tubes Sand at either side of the feet of the upright tubes 9. These plates are placed in the rear end of the heater, so as tocause the products of combustion to pass to the front and not directly towardV the smoke-exitopenings 25. These plates 40 need not be close-fitting. If they direct the major part of the'products of combustion, they perform their offices sufficiently.

What I claim as new, and desire to secure by LettersfPatent, is-

1. The combination with a sectional heater of hollow tooth-like ribproj ections12, the upper surface of which is inclined and the lower surface substantially horizontal, extending across the several sections and lining the iirebox, substantially as set forth.

2. The combination in a heater of hollow sections, the bodies of which are of inverted- U shape having horizontal transverse tubular connections between the arms of the body portiony of lesstransverse thickness'on a horizontal line than that of the body of the sec- IOO IIO

tion and alternately disposed at opposite sides of the section, as shown and described.

3. The combination with a sectional heater havin g' external lugs or projections, of a netting cover adapted to secure composition niaterial, the netting being held by being engaged with lugs or projections and retained 1 thereon by bolts which pass through the lugs or projections and secure the sections of the heater together, substantially as set forth.

4t. A hollow heater-section of an inverted- U-shape forni having` a series of horizontal Witnesses:
